I am currently building a 12 sided house in Groton NY and am considering getting spray foam insulation in the roof as well as a few other locations. Do you provide free estimates? If so I would be happy to review the project with you some evening. Thank you
Bossard Road in Groton
Hi Halco, I would like to request a quote for two possible systems: 1. Geothermal to provide hot water for baseboard heating and hot water, replacing a fuel oil furnace. The house is around 2k sqft. 2. The geothermal above and an 11-12 kW pv solar setup. Thanks, Bryan Gorges
Torok Rd. in Groton
Technician replaced the gas valve, everything seems great. However he also found the exhaust vent was allowing exhaust to enter the intake since they were adjacent and the vent had a 90° T, venting directly next to the intake. He removed the T, which made sense. So now the vent exits directly from the house. However, looking at it, I am a little concerned since the vent is just an open pipe 3 ft or so from the ground, sticking out about 6 inches. Shouldn't there be some kind of cap on the end to prevent weather (rain/snow) and critters (mice/birds) from entering but still allow venting away from the intake? Just looking for a second opinion - perhaps the tech didn't have the appropriate part? I can email a photo of the vent if you wish. Thanks, Greg Weiland Additional information: Preferred Method of Contact: Email

I have an old & inefficient gas-fired residential Weil-McLain Boiler. I was told a year ago it would need replacement "soon". So, I'm looking to get it looked at, and understand what a replacement will cost. I'm open to other suggestions for heating as well.

I have a trailer with an addition over a crawl space. The existing heating ducts are too small. I need the existing ducts removed and replaced with metal ducts.

I just bought a house and would like to know how energy efficient it is. It's drafty in some places and needs a new furnace
Clark St in Groton
We had a geothermal system installed 2 years ago, which has run flawlessly and saved us about 2/3 off our heating bill. UNfortunatly, we recently have had some problems with the system. The heat pump wont stay on very long, therefore not allowing the water temperature to heat up enough for the air handelers. One of the lines serving the loop field has developed a leak where the line enters the flow center. I'm also told that some of the plumbing may have been installed incorrectly, and the temperature senser for the storage tank is also in the wrong place. The company that installed the system has gone out of business (Gleason). I would like to arrange a service person to come out to see if we can diagnose the problem and put together a quote for the needed repairs. It is a GeoComfort brand heat pump. The system has been down for about 2 1/2 weeks, but we have been comfortably heating with wood in the meantime. I should be able to be reached most of the day on Friday 2/8, but my schedule varies. Maybe we can set something up early next week after the winter storm passes. Thank you.
